• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (chieu sang)) - ((hanh mang) OR (nhanh lang)) cua thong thong thanh san tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) OR (chieu sang)) - ((hanh mang) or (nhanh lang)) cua thong thong thanh san tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) OR (chieu sang)) - ((hanh mang) or (nhanh lang)) cua thong thong thanh san tap*.
